the neogene intrusion masses in the noudeh-enghelab area located to the north of sabzevar ophiolite have cut the late cretaceous ophiolitic rocks, sedimentary- volcanic and eocene volcanic rocks and have been covered by pliocene and quaternary deposits. the margin is of lava with basalt, phyric andesite-basalt and andesite and the central parts (dome shaped) composed of phyric andesite-trachyan...
lurestan province is petroliferous area. the reserved oil are in ilam and sarvak (cretaceous ) and kangan ( lower triassic ) and dalan (permian) formations. the lurestan area had high exploration activity but contribution of source rocks in hydrocarbon accumulations isn’t clear. in this paper essential elements and process of hydrocarbon accumulation are introduced. candidate source rocks ar...
The discovery of hydrocarbons (mainly gas) in commercial quantities from Gondwanan sediments in the Mandapeta ®eld of Krishna-Godavari Basin, India, provided impetus for intensi®ed exploration in Mandapeta and the adjoining Kommugudem, Draksharama and Endamuru ®elds. Both oil and gas have been found in the reservoirs of Mandapeta (Triassic) and Golapalli (Early Cretaceous) formations. Mature, l...
study area is located in district of bajestan and ferdows cities, ne of iran. structurally, this area is part of lut block. the oldest exposed rocks, to the north of intrusive rocks and in eastern bajestan, are meta-chert, slate, quartzite, thin-bedded crystalline limestone and meta-argillite. the sedimentary units are: sardar formation (carboniferous), jamal formation (permian), sorkh shale an...
The Bonaparte Gulf Basin Province (USGS #3910) of northern Australia contains three important hydrocarbon source-rock intervals. The oldest source-rock interval and associated reservoir rocks is the Milligans-Carboniferous, Permian petroleum system. This petroleum system is located at the southern end of Joseph Bonaparte Gulf and includes both onshore and offshore areas within a northwest to so...
Acidic and basic volcanic and intrusive rocks of Harzandat-Divan Daghy as individual masses, are located in North and Northwest of Marand (Harzandat) and South of Jolfa (Ghareh Gose-Divan Daghy) trending NW-SE.These rocks are located under Permian progressive deposits, which are covered by an igneous sole unconformity. Lithological composition of the acidic volcanic rocks ranges from dacite, rh...
Gypsiferous soils, as the most characteristic soil in arid and semi-arid regions, are widespread in Isfahan Province. The north-west region of Isfahan is a closed basin and is surrounded by geologic formations. This area is a part of Zayandehrood watershed. The origin of gypsum in this area was investigated in this study. Considering the geologic distribution of gypsum, twenty-two locations, su...

The mineralogy and geochemistry of Paleocene shales and interbedded siltstones in the southwestern of Ahar town (NW Iran) were studied by optical microscopy, XRD, SEM, XRF, and ICP-MS techniques. The mineralogical composition, mainly characterized by calcite, quartz, feldspar, dolomite, muscovite, magnesiohornblende, chlorite, illite, montmorionite, palygorskite, and koninckite, suggests relati...
I sincerely thank my supervisor Prof. Dr. Wladyslaw (Wlady) Altermann and Dr. Michaela Frei. They do not only adviced me on academic issues, but also on my life in Munich. I thank Wlady for accepting this thesis, for respecting my cultural background and for his tolerance towards my ideas and behaviours. He was always encouraging me, which give me confidence to progress in my research work. Mic...
